The internal temperature sensor located in almost all ACR data loggers is the ET-016 thermistor. Thermistors
are non-linear which means the accuracy of the sensor varies over the entire temperature range of the logger.
The graph below outlines the accuracy curves for the ET-016 thermistor. ACR data loggers with this thermistor
on-board include: SmartReader, SmartReader Plus, OWL (if using standard range), JR, and Nautilus. These
curves also apply to the ET-016 external thermistor probes with lengths less than 30 meters (100 feet).
